Nondirectional radio beacon (NDB) is defined as what?

Explanation:
An NDB is a ground-based radio transmitter that radiates energy equally in all directions. This nondirectional pattern lets an aircraft use an Automatic Direction Finder to determine the bearing to or from the station. It’s not a satellite-based system, it doesn’t emit a directional azimuth from the beacon itself, and it isn’t an airborne transponder beacon. The key idea is that the station itself radiates uniformly in all directions, and the airplane’s receiver helps the pilot establish a bearing to the station.
